I think there is some bug in online assembler. But I cannot investigate it b/c I didn't have any ARM Thumb2 env....... 1180876 8 zan 2016-04-05 11:02:20 -0700 Bug #150083 has a WIP patch that addresses two places where tail call linking wasn't properly working on Thumb2 platforms on Linux. Bug #154857 probably has more in common with that problem, but I was not experiencing a larger set of JSC test failures with GLib timers when testing with r198847 in release or debug builds, apart from a few failures due to internationalization and timezone settings in the testing environment. 1183019 9 ossy 2016-04-12 01:39:14 -0700 *** This bug has been marked as a duplicate of bug 150083 ***
